History is big business. Plundered art and antiquities trade to the tune of at least $3 billion a year, much to the chagrin of nations struggling to reclaim their lost artifacts. In honor of a recent spat between the Egyptian government and the Louvre museum in Paris over the fate of fresco fragments, TIME examines 10 plundered antiquities and the conflicts they've created.

Nefertiti's Bust

During a 1912 Egyptian excavation, German archaeologist Ludwig Borchardt discovered the bust of Nefertiti, a 14th Century BC Egyptian queen. He claimed to have an agreement with the Egyptian government that included rights to half his finds and  using this as justification  Berlin has proudly displayed the item since 1923. But a new document suggests Borchardt intentionally misled Egyptian authorities about Nefertiti, showing the bust in a poor light and lying about its composition in order to keep his most-prized find. The Egyptian Supreme Council of Antiquities has repeatedly asked Germany to give the bust back  or at the very least let it return home on a temporary basis.

Current Status: Germany insists their ownership of Nefertiti is without doubt, and Berlin's Egyptian Museum curators maintain that even a brief loan may damage the bust.
